Spark Plug - Installation

INSTALLATION

CAUTION: Never use a motorized wire wheel brush to clean spark plugs. Metallic deposits will remain on spark plug insulator and will cause plug misfire.

CAUTION: Do not attempt to clean any of the spark plugs. Replace only.

1. To aid in coil installation, apply silicone based grease such as Mopar(R) Dielectric Grease into spark plug end of ignition coil rubber boots. Also apply this grease to the tops of the spark plugs.





2. Check and adjust spark plug gap with a gap gauging tool (1) Spark Plug Specifications.

CAUTION: Due to tight clearances a conventional deep, thick-wall spark plug socket will not fit. Use a deep, THIN-WALL 5/8" spark plug socket for plug removal and installation.

NOTE: Do not drop spark plugs into the plug wells as electrode damage can occur.

3. Using special care install the spark plugs into the cylinder head spark plug wells by hand to avoid cross threading.

NOTE: Always tighten spark plugs to the specified torque. Certain engines use torque sensitive spark plugs. Over tightening can cause distortion resulting in a change to the spark plug gap, or a cracked porcelain insulator.

4. Tighten the spark plugs to the specified torque Spark Plug Specifications.
5. Install the ignition coil(s) Ignition Coil - Installation.
6. Install the necessary air filter tubing and air intake components to the top of the engine and to throttle body.
